The Denver Broncos agreed to terms with free-agent OG Steve Vallos (Jaguars) Sunday, July 28, pending his physically, executive vice president of football operations John Elway announced. Terms of the deal were undisclosed.

Cleveland Browns C Steve Vallos, who might start in Week 6 against the Oakland Raiders if C Alex Mack (appendix) cannot go, is confident he'll be able to work error-free with QB Colt McCoy. "I was the scout team center, and (McCoy) was the scout team quarterback," Vallos said. "This isn't our first time snapping to each other."

Updating a previous injury, Cleveland Browns C Alex Mack (appendix) had an appendectomy Monday, Oct. 3, and everything well well, according to head coach Pat Shurmur. If Mack cannot play in Week 6 after the bye, either OG John Greco or C Steve Vallos would likely replace him. OG Shaun Lauvao has also practiced at center, but he is likely to remain at right guard.
